To all whom it v:may concern:

Be it known that I, ALBERT A. GORDON, \Jr., a citizen of the UnitedStates, residing `at Worcester, in the county of Worcester and State ofMassachusetts, have invented certain new and useful Improvements inThread-Cutting Temples for VVett-Repvlenishing Looms, of which thefollowing is a specification.

My invention relates to a thread cuttino` temple for weft replenishinglooms, an particularly to the type of thread cutting temple shown in U.S. Letters Patent, No. 5555,465, in which the filling or weft threadcutting mechanism is lcombined with the loom temple. In said patentedcutting teinple, the cutting mechanism comprises a statioiiary cutter orblade, and a movable cutter or blade; the movable cutter has a heel orextension thereon, which, 'on the. forward movement of the lay, isengaged by a projection on the lay, and through said engagement saidcutter is moved to cut the filling which extends out beyond the selvageof the goods, in case said filling has been caught by the hook on saidmovable blade, all as fully described in said patent.

It has been found in thepractical use of the patented thread cutting temle` above re terred to, that the end of the filling extending out fromthe selvage or edge of the -fabric, after the transfer of a bobbin fromthe magazine into the active shuttle, and the picking of said shuttlethrough the shed from the magazine end of the loom, and alsoparticularly where a shuttle having a substantially exhausted bobbin ispicked from the end of the loom opposite from the magazine, and ysaidbobbin is then expelled from the shuttle by the insertion of anewbobbin, that the filling will not be cut by the cutting mechanism,because the forward movement of the lay has moved the movable cuttertoward the breast beam, be- Ltoie the illing has been beaten up by thereed suliciently to be enga ed by said cutter, and consequently the lingend is lett outside of the'selvage, and is liable to be drawn into theshed by the shuttle, or by subsequent shots of illing.

To overcome this fault in, and objection to'thc patented thread cuttingmechanism above referred to, it is necessary 'to add an independentcutting mechanism, between the temple cutting mechanism, and the'direction of arrow 11, same figure.

magazine, to cut the fillin whichfis not cut by the temple cutting mecanism.

The object of my invention is to improve upon the type of threadcutting4 tem les shown and described `in said Patent, glo. 585,465,.andmore particularly to do away with a second c utting mechanism, and tocombine with the atented thread cutting mechanism, a supp ementalmechanism, by means of which, on the ,transfer of a bobbin from themagazine into theyactive shuttle, and the expulsion ot' thesubstantially exhausted bobbin from said shuttle, the movement of themovable cutter will be delayed until the lay has advanced almost to itsforward position, and until the filling is moved forward sufficiently bythe reed, to be in a position to be engaged by said movable cutter,which is then moved, preferably independently or' the, movement of thelay, by a supplemental mechanism, the operation of which is controlledthrough connections to the transferring mechanism at the magaziney endof the loom.

My invention consists in certain novel features ot' construction of myimprovements as will be hereinafter fully described.

I have only shown in the drawing a detached portion of a weftreplenishing loom,

and piarts of a weft replenishing mechanism, Whic are shownandsdescribed in U. S.

thread cutting temple .of the type shown anddescribed in Patent, No.585,4435, above referred to, with my improvements combined therewith,suflicient to enable those skilled Iin the art to understand thcconstruction and opera-tion of my improvements.

Referring to the drawing: Figure l is a rear view of a detached portionof the breast beam of a loom, with a part of the weft rcplenishi'ngmechanism thereon, and a thread `cutting temple, and my improvementscombined therewith, looking 1n the direction of arrow a, Fig. 2. f Fig.2 is a section, on line 2, 2, Fig. l, looking in the Fig. 3 is asection, on line 3, 3, Fig. 2, looking in the direction of arrow c,lsame figure.V Fig. 4 shows, on an enlarged scale, the cutter blade, andparts. connected therewith, de tached, looking in `the direction ofarrow a3, Fig. 5. Fig. 5 is an end view of the parts shown in Fig. 4,looking in the direction of arrow e, saine figure.

In the accompanying drawing, 1 is a detached portion of a-loom side orend frame, 2' the breast beam3, Fig. l, is the lower portion of thestand on which is supported the magazine, noty shown, for the bobbiiisor lilling carriers. The stand 3 carries astud, on which is pivotallymounted the hub 4 of an arm 4 of the transferring mechanism. A boss 4 onthe arm 4 carries a stud 5', which is pivotally connected to the upperend of a vertically moving plate 5. A lielically coiled tension spring4, acts to move the arm 4 of the transferring mechanism, in the usualway.

The lower enlarged part 5 of the plate 5 has loosely extending thereinthe upper end of the vertically moving rod 6, see Fig. 1.

7 is a longitudinal pin or rod,-suitably supported and guided in a sideextension or arm 5 on the plate 5. The outer end of the longitudinal pin7 is adapted to be engaged by a lever, connected with the fillingdetecting mechanism, and moved -in'wardly against the action of ahelically coiled expansion spring S mounted on the pin 7, to bring theinner end of the rod 7' in the path of the upper end of the verticallymoving rod G. The pin 7 has a collar 9 fast thereon, which carries awire 10 having an eye 10 on its inner end, through which loosely eX-tends a vertically moving rod 11. Through the longitudinal movement ofthe pin 7 the rod l1 is moved out or in at its upper end.

All of the above mentioned parts are of the same construction andoperation as the similar parts shown and described in the LettersPatent, No. 948,568, above referred to.

The upward movement of the rod (3, when the inner end of the pin 7extends in the path of the upper end of said rod, will move upwardly theplate' 5, against the action of the helically coiled contraction spring12, to

operate the arm 4 of the transferring mech-I anism, and throughintermediate connections, not shown, raise the dagger,iiot shown, tocause the transfer of a new bobbin, in the 'usual way.

I. will now describe the thread cutting loom temple shown in thedrawing, and which in this instance corresponds to the loom temple shownand described in latcnt No. 585,465, above referred to. The loom templecomprises the stand 13, see Fig. 2, which is secured to the-plate 2 onthe breast beam 2. The stand 13 is adapted to hold the slide bar 14 ofthe temple. 'llie slide bar 14 y has a head 14 on which is secured thecap 15. The temple roller or burr 16 rotatably mounted within the cap15. The head 14 isrecessed to receive a stationary blade 17. l Themovable cutter or blade 18 is at its front end made of substantially thesame Shape as the movable blade in said patent. No. 585,465, the frontend being slotted and of hook shape. The slotted end of the blade 18straddles the stationary plate 17. In its normal or inoperativeposition, the inner or front end of the cutter 18 is, by the action ofthe spring 19, kept projecting through the slot in the head 14, andelevated.

The spring 19 is. connected at one'end with a stud 14 on the bar 14',and at its other end with a stud 18 on a downwardly extending projection18 on the cutter 18, and as above stated, acts to yieldingly hold theand return it to said position.

All of the above mentioned parts of the thread cutting temple are of theusual and well known construction, shown and described in said Patent,No. 585,465.

l will new describe my improvements combined with the parts of thethread cutting temple above described. On the breast beam 2 at themagazine end, is in this iiistance secured a downwardly extending standor bracket 2O carrying a stud 20', on which is loosely mounted the hubQ1 on the lower end of an upright lever 21, see Fig. 1. A sideprojection 21 on the lever 21 extends in and is adapted to engage thelower end of the enlarged part 5 on the vertically moving plate 5. Ahelically coiledcontractioir spring 22 is att-ached at one end to theside extension Q1 on the lever 21, and at its other end 4in thisinstance to a pin 23 on the rear of the breast beam 1. Said spring. QQacts to yieldingly hold the side extension part 5 of the plate5.

lVhen the pla-te 5 is raised, during the op- ,eration of transferring afresh bobbin or filling carrier from the magazine into the runningshuttle, and the expulsion of the substantially exhausted bobbin fromthe running shuttle, the upper end of the lever 2l is moved to the rightin Fig. 1, through the vaction.of the spring 22. On the upper end of thelever 2l is a stud 24, to which is ivotally connected one end of a rod25.

2G on a bracket 9.6 secured to the rear side of the breast beam 1, andthe inner end of said rod 25 is adapted to engage a side cxt'ension 27on a downwardly extending arm or lever Q7, which has its hub Q7pivotally mounted on a bolt or .screw Q8, see Fig.' 4. The bolt or screwQ8 isv fast in an extension or heel 18 on the cutter blade 18. Extendingupwardly from the hub 27 of thc lever Q7, is an arm 27', in thisinstance having blade 18, seel Figs. 4 and 5, and acts to limit thepivotal movement of the lever Q7 in one direction, as shown by fulllines in Fig. 3.

A helicall coiled contraction spring 29 is attached at its lower end toa pin 30 on the hub 27 of the lever 27, and at its other end to a pin 31on the slide bar 14, see Fig. 2;

patent, and this movement takes place on tion 3G thereon will pass bythe lever 27,

"with the drawing, the operation of my iinvior heel of the movab ecutter 18, will extend said spring 29 acts to yieldingly hold `the lever27 in the position shown by full lines in Fig. 3, and to return it tosaid position.

A stand 32 is secured at its upper end on the inner side of the breastbeam, see Figs. 1 and 2, and carries at its lowerend a boss 32', inwhich is held a stud 33, on which is lever V34. The lower arm oi thelever 34 is connected with the u per end of a rod or connector 35, whichrot is operated throng", mechanism, not shown, preferably a cam' lever,and a cani on the bottoni shaft of the loom, to operate said connector35 and the lever'34 every other pick of the loom. The upper arm 34 ofthe lever 34 has a sideextension 34 thereon, which is adapted to extendin front of the lever 27, see Fig.

i From the above description in connection provements, combined with theloom temple cutting mechanism shown in the drawing,

. In the normal operation of the loom, the arm or lever 27, sup orted onthe rear end in the path of a projection on the lay, said projection isindicated by broken lines 36 in fig. 4, and as the lay beats up, saidrojcction' 36 will engage the arm 27 an move backwardly the cutter 18,to cause it to engage and cut a filling 01'v weft thread, in case thereis :any filling or weft thread under the hooked end of said blade, inthe same manner as described in said Patent, No. 585,465. As statedabove, this is the only backward movement of ihecutter 18, in said everyforward movement of the lay. without l regardto the transfer ot' a newbobbiii from the magazine, and the expulsion of the substantiallyexhausted bobbin from theactivc shuttle.

In the operation et' my improved construction ot cutting mechanism, whenthe bobbin is to be transferred from the niagazine into the, activeshuttle, and the substantially exhausted bobbni in said shuttle'is to beexpelled from the shuttle, the operation of the transterrer arm 4,tlirou h the upward movement of the rod 6 and the plate 5, Iwill releasethe lever 2l, and allow the spring 22 to act to move the rod 25 tothe'right, Fig. 1, to cause it to engage the side extension 27 on the lever27, and move said lever 27 to one side, as indicated bv broken lines inFig. 3, and out of the path of the projection 36 on the lay, so that asthe lay advances on its forward movement, the projecleaving the movablecutter 18 stationary, and said cutter `vfill remain stationary, andallow the filling extending out beyond the relvage to be beaten up bythe reed and pass b v broken lines in Fig. 3, and move said lever andwith it the cutter 18 backward,

causing the cutter 1S, in connection with the stationary cutter 17, tocut or sever the filling. Flne return movement of the transtcror aim 4to its normal position, and the atlcnward movement of the plate 5 androd l(i, will cause, through the engagement of the' enlarged part 5 onthe plate 5 with the side extension 21 on the lever 21, the movement ofsaid lever 21 to the left, Fig. 1, against the action of the spring 22,and also the movement of the rod to the left, Fig. 1, to release` thelever 27, and allow the spring 29 to act, to return said lever to itsnormal position, and out of tne path of the side extension 34 on thelever 34, as shown by full lines in Fig. 3.n The cutting mechanism willthen continue to operate, that is the movable cutter 18 will be movedback at every forward movement of the lay, by the engagement of theprojection 3G, (see Fig. 4,) with the lever 27, until, on the trans-"fer of another bobbin from the magazine into the active shuttle, mymechanism above described is again put into operation.'

The advantages oi my improvements will be readily appreciated by. thoseskilled in the art. I

lt will bA Aiinderritood that in the normal operation of the loom, themovable cutter' of the cutting mechanism has a movementl comi-iunicatedthereto by the forward movement. of the lay, in the saine manner asdcscribed in said Patent, No.` 585,465, but that on the transfer of anew bobbin from thc magasine into theactivev shuttle, and the expulsionof the Substantially exhausted bobbin from sa'd shuttle, thc movement ofthe cutter 13 delayed until the reed has moved forward the filling orwei't thread `suiiiciently to be engaged by the hooked end of the.cutter 1o, and the-n the said cutter 18 is moved independently ot' thelay, to sever or cut the tilling or wett thread. ln this way Iaccomplish with one cutting mechanism, and my supplemental mechanism foroperating the cutting mechanism, which supplemental mechanism ispreferably operated indepe idently ot' the lay, whenever there is abobbin oir-filling carrier transferred from the magazine, what hasordinarily required two cutting mechanisms.

ltwill be understood that thc details of construction of my improvementsmay be varied it desired. ll'ly supplemental mechanism is preferablyoperated independently of the lay, but it may be operated throughconnections to the la Having thus described my invention, what and themovable cutter, to cut or sever the or weft thread.
